AI Technical Summary

Technical Problem

The 5G NR system faces challenges in managing the maximum quantity of blind detections and channel estimates for user equipment due to increased configuration of CORESETs, potentially exceeding the UE's processing capabilities, especially in multi-TRP scenarios.

Method used

A method for discarding or reallocating search spaces to manage the quantity of PDCCH candidates and non-overlapping CCEs within the UE's processing limits, including discarding search spaces associated with specific TRPs or CORESETS to prevent overbooking and maintain compliance with processing limits.

Benefits of technology

Reduces the likelihood of exceeding maximum PDCCH candidate and channel estimate limits, enhances flexibility in resource allocation, and decreases complexity and power consumption for the UE.

Abstract

Provided are a search space distribution method, a search space configuration method, and a related device. The method comprises: when a terminal device is configured with a TRP, if the number of first monitoring targets of a search space set configured for the terminal device exceeds an upper limit of first monitoring objects, the monitoring of which is supported by the terminal device, then discarding some search spaces configured for the terminal device, wherein the first monitoring objects comprise PDCCH candidates or non-overlapping CCEs.
